Can holes be drilled in the walls of Class A factories to install air supply fans?
Thread Content
I would like to ask: Is it possible to drill holes in the walls of a Class A factory building to install air supply fans? Since the fan opening is not sealed, it is not possible to ensure airtightness between the inside and outside of the fan’s opening
Why maintain closure? Class A factories should also maintain good ventilation; the gaps between the fans and the walls should be sealed properly, and the fan outlets are equipped with built-in louvers
Ventilation openings must be provided; otherwise, how can the volatile gases be expelled?
This practice is no longer allowed. :lol:lol
Exhaust fans are okay, but supply fans won’t work
Sure, except for the firewall. Firewalls must have no gaps and cannot pass through pipes. See GB50016
Sure! Our assembly plant is equipped with side wall fans, and ventilation must be turned on during production.
If the fan is installed on the exterior wall and it is not a fire wall, then there is no problem. Generally, the exterior walls of Class A factories are designed to allow for explosion venting, so fans can be installed there.
All I saw were exhaust fans; I really didn’t see any supply fans.
